ABSTRACT

This thesis report describes an online intelligent multiple-choice- question examination system, named Online Intelligent Quiz System (OIQS), for students. Any university, college or school with a computerized education system can adopt this system. Teachers can administer quizzes using the OIQS. There is an expert part in our system, which uses AI to generate questions. The system will determine the participant's performance depending on his answer and the next question will be generated according to the participant's performance. The system will show result after the examination is finished and also be able to provide feedback according to the participant's demand. Administrative control of the whole system is provided. A teacher has control in the question bank and is suppose to make schedule for quiz. 5

1.0 INTRODUCTION

This is a web-based intelligent multiple-choice-question examination system, named Online Intelligent Quiz System (OIQS), for assessing students. It is a system by which students can appear in a quiz from anywhere of the world where there is no interaction between pencil and paper rather interaction between computer and human being. We use the term intelligent here as the system generates questions intelligently. There are many definitions of intelligence but we use the term intelligence in the sense that the system generates the a new question of a quiz by depending on the result of the question last answered and for the same quiz of a subject it generates different questions for different students. The questions vary student to student for the same quiz while they are sitting in the quiz at the same time. Teachers can use the OIQS for evaluating students effectively, efficiently and perfectly. Any university, college, school or educational institute can use this system for their organization to take quizzes. Today it is the more efficient and effective methods of assessing distant students. One of the main benefits of our system is automated marking, that is, teachers do not need to check the answer script as they do in manual quiz. It saves valuable time of a teacher. On the other hand, students can score according to his/her merit level and it will give feedback about a student in which side he/she is weak. In recent years, the use of online quiz systems has become quite popular due to pressures of increasing class sizes and the need for more efficient and effective methods of assessing distant students. It is due to the popularity of distant education. 9

2.0 CURRENT SCENARIO OF QUIZ SYSTEM

Still now maximum educational institutes have been using manual system to take quiz. In the recent year a few instructors of some institutes have been using web-based M.C.Q. quiz system. Actually, it depends on how much web technology a country takes or uses. For example, in Bangladesh it is rare to use a web based quiz system. But in case of U.S.A. it is a general case to use a web based quiz system.

2.1 MANUAL QUIZ SYSTEM

In the early days it was the most popular methods of assessing student. Still now the system is quite popular to the students as well as to the teacher. In this system there are several problems that we faces in a common way. Some of those problems are:

Manual system requires pen/ pencils and paper.

Teacher needs to spend time to script checking.

Student needs to wait to get their result up to the teacher finishes the script checking. These are the most common problems of manual quiz system that rotated each and every time of quiz held. For these causes the popularity of manual system decreases day by day and online intelligent quiz system is taking the place of the manual system.

2.2 WEB BASED QUIZ SYSTEM

Now a day the web base quiz system is getting popular with a tremendous speed. As the technology is spreading through out the world the automated system will also taking the places of the manual systems. Currently big institutes are running their online quiz systems at a very successful rate. As the time is progressing the online quiz is making interest to the faculties and also to the students. In the big cities and organizations people are getting understand that how the online quiz system is better and efficient. With in the recent time this system will be taken place to this techno world. But this system also has some lacking. If this system has the intelligent part then it will be a perfect one. The problems that may occurs with web based quiz system:

Can't evaluate the student perfectly.

Can't generate the proper feed back of the students. 10

3.0 FEED BACK FROM CURRENT SCENARIO

From the previous two systems I realize to solve the problems of those systems to get a standard quiz system. In the previous two systems the things that are short from a standard quiz system, to fix it up I design an intelligent system, which will work according to the web base system. From this intelligent system we can omit the manual system's problem criteria because it work as a web base system, which is totally automated. It also omit the general web based system because it gives the evaluate option for the students performance and feed back criteria. To get a standard quiz system I tried to join the intelligent system that I designed for my thesis project. This will help to remove the current system's problems. 11

4.0 PROPOSED SYSTEM

In recent years, the use of electronic online quiz systems has become quite popular due to pressures of increasing class sizes, and the need for more efficient methods of assessing distances students. This thing motivates us to work with web based quiz system. We also have tried to eliminate the problem with general web based quiz system and decide to create a web based intelligent quiz system. In our thesis project, we have tried to develop an "Online Intelligent Quiz System" which will be popular in both the students and teachers. To develop the system we collected some documents from web. Then we have analyzed those documents and tried to find some logic from there. As a step of development we collected requirements where we have conducted a survey. In that survey we took teachers and students opinions to make the system more meaningful. For that we made a question set and gave it to some teachers and students. They gave their opinions on those scripts. In below survey details are given.

4.1 SURVEY

To make an effective and efficient Online Intelligent quiz system we need some findings. We believe that our findings will help us to make the system user friendly. Here is a short description of our system. Our system name is Online Intelligent Quiz System. Any University, College or School can adopt our system where education system is computerized. Teachers can take quizzes using our Online Intelligent Quiz System. We will use an expert part in our system, which is knowledge base. This expert part will work using AI. Our system will determine the participant's performance and the next questions will be generated according to the participant's performance. Our system will also be able to provide feedback according to the participant's demand. 12

4.1.1 TEACHER'S SURVEY

We create this question for teachers to find out what type of system might be helpful for them.
